What it is about

Red Hat Enterprise Linux (RHEL) ist eine populäre Linux-Distribution. Ein entfernter, anonymer Angreifer kann mehrere Schwachstellen in Red Hat Red Hat Hardened Images RPMs ausnutzen, um Sicherheitsvorkehrungen zu umgehen, einen Denial-of-Service-Zustand verursachen, vertrauliche Informationen offenlegen oder nicht näher spezifizierte Angriffe durchführen, einschließlich potenzieller Codeausführung.

Under what conditions?

Over the network and without logging in. This is the most dangerous combination: attackers can scan reachable devices automatically.

What can happen in the worst case

An attacker could use the vulnerability to

  • Sicherheitsvorkehrungen zu umgehen
  • einen Denial-of-Service-Zustand verursachen
  • vertrauliche Informationen offenlegen oder nicht näher spezifizierte Angriffe durchführen
  • einschließlich potenzieller Codeausführung

Am I affected?

Affected according to the BSI:

  • Debian Linux
  • Amazon Linux 2
  • Red Hat Enterprise Linux
  • Ubuntu Linux
  • SUSE Linux
  • Oracle Linux
  • Red Hat OpenShift Container Platform
  • RESF Rocky Linux
  • Red Hat Enterprise Linux Hardened Images RPMs pyOpenSSL
  • Red Hat Enterprise Linux Hardened Images RPMs jq
  • Splunk SOAR <8.5.0
  • Red Hat OpenShift Container Platform <4.13.68

and 1 more

The installed version is usually shown under “Help → About” or in the device’s admin interface.

What helps?

Update to at least:

  • Splunk SOAR 8.5.0
  • Red Hat OpenShift Container Platform 4.13.68
  • Meinberg LANTIME V7.10.013

Is the vulnerability already being exploited?

None of the CVEs is in the CISA catalogue of exploited vulnerabilities. That does not mean there are no attacks, only that none are documented.
